PRODUCT INFORMATION
Product Overview
The ABB NTAI02 is an analog input termination unit designed for the Bailey INFI 90 distributed control system. It provides connection interfaces for field instrumentation directly to system processing hardware. The assembly routes analog signals securely into the control architecture. It handles sixteen thermocouple or millivolt inputs per unit. This unit supports stable field signal management across process automation environments.
The unit operates from a 24 V DC power supply source. Circuit protection includes an integrated 0.25 A fuse rated for 250 V service. The module maintains operation across an operating temperature range of –40 to 70 °C. These environmental specifications allow deployment in challenging industrial plant control cabinets. Plant technicians use this module to terminate low-level analog wiring cleanly.
